We're expecting to see the redesigned 911 unveiled later this week, but Autocar's spies have caught the next iteration of the GT3 RS running at the Nurburgring ahead of its unveiling later next year. As is often the case with Porsche, it's hard to discern any substantive differences between this newest version of the GT3 RS and the current model, but when the new 911 makes its debut, it'll be wearing a redesigned front bumper, along with LED headlights and taillights, all of which will carry over to the GT3 RS.

Granted, these subtle changes aren't that compelling, but Porsche has big plans for what's underneath the new model's sheet metal. The GT3 RS will supposedly be packing another 40 hp over the outgoing model, developing 450 hp at peak output. However, there's been considerable debate about whether or not the GT3 RS' engine will be equipped with direct-injection, considering it's traditionally been based off the GT1 racecar. Harnessing those extra ponies will be a seven-speed, dual-clutch transmission (Porsche Doppel Kupplung or PDK in Porsche parlance) that will provide seamless and ultra-quick shifts through steering wheel-mounted paddles. Purists might complain about a lack of a manual gearbox, but that's what purists do. So expect a manual version to be an option when it goes on sale in late 2009 or early 2010.
